What are the characteristics of ultra high molecular weight polyethylene?

May 16, 2019

The ultrahigh molecular weight polyethylene sheet is a polyethylene having a molecular weight of 1,000,000 or more. The ultra-high molecular weight polyethylene sheet wears 1-7 times of the steel plate. It differs from the steel plate in that the steel plate is not resistant to acid and alkali, and the high molecular polyethylene plate is resistant to acid and alkali. The long-term exposure of the steel plate to the oxygen molecules in the air in the air The reaction produces rust, and the ultra-high molecular polyethylene sheet is not corroded. Today, Tangyin Xinxing Plastics Co., Ltd. talks about the characteristics of ultra-high molecular weight polyethylene sheet, and hopes to help you. Ultra high molecular weight polyethylene has many features.

The first is high wear resistance. A performance that is compelling for molecular weight polyethylene is its high wear resistance, which is invaluable in many engineering applications. In all current plastics, the wear resistance is good, and even many metal materials (such as carbon steel, stainless steel, bronze, etc.) are not as abrasive as regular ones. As the molecular weight of polyethylene increases, the material becomes more wear resistant.

Extremely high impact resistance. The impact strength of ultra-high molecular weight polyethylene is related to its molecular weight. When the molecular weight is less than 2 million, the impact strength increases with the increase of molecular weight, reaching a peak at about 2 million. At this time, the molecular weight increases the impact strength instead. Will fall. This is because the molecular chain is very obstructive to its photonic action, so that there is a large amorphous region in the macromolecule and thus can absorb a large impact energy. Ultra-high molecular weight polyethylene sheet is a linear structure of thermoplastic engineering plastics with excellent comprehensive properties. Fiber is the third generation of special fiber in the world, with a strength of up to 30.8cN/dtex, and the specific strength is high in chemical fiber. Good wear resistance, impact resistance, corrosion resistance, light resistance and other excellent properties.

Due to the many excellent properties of ultra high molecular weight polyethylene. It offers significant advantages in the high performance fiber market, from mooring lines in offshore oil fields to high performance lightweight composites. Ultra-high molecular weight polyethylene sheet can be used as a lining for trailers, silos, and chutes for loading coal, lime, cement, mineral powder, salt, grain, etc., because of its excellent self-lubricity and non-stickiness.

The above-mentioned powder file can be used for the storage and transportation facilities without sticking to the scene, and the guarantee is guaranteed. In industrial applications, it can be used as pressure-resistant containers, conveyor belts, filter materials, automobile buffer boards, etc.; construction can be used as wall, partition structure, etc., using it as a reinforcing cement composite material can improve the toughness of cement and improve Its impact resistance.

Due to its excellent wear resistance and impact resistance, it is widely used in the mechanical manufacturing industry to produce a variety of gears, cams, impellers, rollers, pulleys, bearings, bushings, bushings, shafts, gaskets, Mechanical parts such as gaskets, elastic couplings, and screws.
